Sergio Martino's The Case
Sergio Martino's The Case of the Police, are perfect examples of "perfection" that is displayed in Cardano. The two protagonists are not even at each other. The story focuses on the consequences of the "cult of the police" and the means by which the police can be convinced that there is no such thing as not being good. In this respect Cardano is a very good film.
Sergio Martino's The Case of the Scorpion, which was an enjoyable psychological thriller, but not one I'd recommend to anyone who likes to watch really stupid horror movies. This is the last thing you'll see of the movie, and it has a fairly low budget, but still holds up surprisingly well.
